Question

I like to use std::ostrstream to format text but not print it to stdout but instead write it into an std::string (by accessing the std::ostrstream::str() member). Apparently this is deprecated now. So, how am I supposed to write formatted objects to a string, with the same convenience as when writing to a stream?

Answer 1

You could use std::ostringstream. Similarly, instead of std::istrstream you should use std::istringstream. You need to include the <sstream> header for these classes.

You could also see this question which explains why strstream was deprecated.
